CVE-2025-47736Public exploit

Process crash via unchecked UTF-8 conversion

Published May 9, 2025 · Updated May 9, 2025

Improper invalid-input handling in gwenn libsql-sqlite3-parser 0.13.0 and earlier allows local users to crash a consuming process. The dialect/mod.rs from_bytes helper passes parser-controlled bytes to unsafe str::from_utf8_unchecked and constructs a String without validating UTF-8. Reachability requires a consuming application to pass invalid byte sequences into the parser; exploitation interrupts only that process, with no reported data disclosure or modification.
